The Stop Trump Ireland coalition will full today give details about protests they will stage during the US president's visit to Ireland.
The coalition includes more than 30 organisations, including human rights and anti-racism groups.
Donald Trump is due to arrive in Ireland on Wednesday for a brief visit.
Memet Uludag, convener of Stop Trump Ireland, says the main protest will take place in Dublin on Thursday at 6pm at the Garden of Remembrance although President Trump won't be visiting the capital.
Protestors says they are marching in Dublin to attract the most amount of people.

Other groups such as Shannonwatch, Extinction Rebellion Clare and Futureproof Clare say they will hold a protest at Shannon Airport on Wednesday at 6pm.
It's not clear how close protestors can get to the facility as tight security will be in place around Shannon Airport and the Doonbeg Golf Resort in Co.Clare for the President's visit.
He will spend two nights at Doonbeg before returning to Washington on Friday.
